Pixels:3D
offers many tools to help you manipulate spline meshes
in different ways, but personally often find a rather
direct approach to shaping my models most rewarding. For
the purposes of this tutorial, I will be working almost
exclusively in Tag mode using the Control>Move, Control>Rotate
and Control>Scale tools.

Begin
by reshaping the right end of Pointer as shown in (Figures
4 & 5). Work mostly in the Right View window, using
other views to reach indivdual or hard to select CVs.
Hold down the Command key to Tag points and Shift-Command
to add/subtract from the current selection. In this case
use the Control>Move tool to drag the CVs into position.

In
order to make the shapes I am creating as clear as possible,
I have turned off surfaces and shaded previews for much
of the tutorial.

By drawing the V steps closely together as I am at the
bottom of Pointer, and bringing several CVs up sharply,
I am creating a slight kink in the surface that will represent
the crease on the underside of the finger where it attaches
to the palm. To view the result of this turn on surfaces
for a minute and examine how the shape of the hull effects
the mesh surface.

Move
to the next set of three V steps, and reshape them as
seen in (Figure 6). Once again I am drawing the mesh together
at the bottom to create the crease between the first two
joints of the finger, and pulling some CVs up and out
to create the hump of the first knuckle.
